Magnet not only levitates metal but melts it

Levitation and warming effects is possible at home that is if you have a chance of finding a specialized electrical equipment and a couple of devices.

The video below demonstrates a bit of metal drifting in a loop and afterward liquiefying. How this happens? Is it enchantment or just material science?

To start with the levitation. On the off chance that you run an alternating current, which can be found on the outlets of every house, through coils you produce a magnetic field that progressions with time. House current would roll out it improvement 60 times each second. (That is the "60 Hz" you see imprinted on the power connectors and apparatuses when it says what sort of power source you can attach them to). So the field all things considered will waver at 60 hertz.

Placed something in a magnetic field — like a lump of aluminum — and the molecules in the material will create little currents called eddy currents and flows that produce little magnetic fields of their own. On the off chance that the material is diamagnetic, which fundamentally implies it doesn't stick to magnets, then the little magnetic fields will be inverse to the one in the coil, and create a force that repulses.

This is generally the same rule utilized as a part of magnetically suspended trains, which skim over their tracks to achieve high speeds.

Notwithstanding utilizing a bit of aluminum, the experimenter likewise utilized an electric inverter to substitute the current at 204,000 times each second, a much higher recurrence than what you get from an outlet. It's likewise not clear the amount of current and voltage is being utilized.

Next up is the warmth. The metal melts due to a standard called induction heating — the same rule utilized as a part of induction stoves.

The warmth originates from the magnetic field that suspends the bit of metal. Keep in mind the vortex streams that are produced in the aluminum? Those currents experience resistance, and in doing as such warmth the metal up. The more resistance, the more heat.

The bit of metal here is additionally really little — just 2.6 grams, or about the heaviness of a few medium-sized paper cuts. So it doesn't take a considerable measure of energy to soften it.
